This post on Steam announces the release of new free content for the Windows edition of Earthfall, the cooperative first-person shooter. This includes new skins, a new progression system, and an overhaul of melee weapon audio. Here's the news:

The update introduces the devastating new ValkBait grenade, a host of new skins, an extension of the player progression system with levels 51 through 65 and updated audio design for melee weapons.

Led by Oscar-nominee Alan Rankin, renowned Hollywood sound studio Formosa Group was brought on by Holospark earlier this year to completely revamp Earthfall’s sound design. Players were first able to hear the improvements in October’s Invasion Update, which updated the audio of the game’s ballistic weapons. In this update, players will hear improved and realistic audio for the game’s melee weapons.
